Do you have a multiple choice selection of answers, because there is no way to pick a job out of the blue without certain choices and a math problem set up.
She could make 20 servings of lasagna.
There are 4 servings per pound of lasagna, and there are 5 pounds total.
4 x 5 = 20
Answer:
63.2 = y
Step-by-step explanation:
The perimeter is the sum of all the sides
P = 7.8+ y+37.6 + y
171.8 = 7.8+ y+37.6 + y
Combine like terms
171.8 = 45.4 + 2y
Subtract 45.4 from both sides
171.8-45.4 = 45.4 + 2y -45.4
126.4 = 2y
Divide each side by 2
126.4/2 = 2y/2
63.2 = y
The square root of 24 simplifys to:
√24
2√6
Since √6 is inbetween √4 and √9, it is somewhere in between 2 and 3. Really, the best option is to use a calculator.√24 is approximately 4.9. <span />
